So, I really hated the fact that every time I went on the freeway I would get great speed, but when I was driving on local roads, that speed just wasn’t there. But then I was at the shop talking to my buddy mechanic, and he said that what he did for his BMW e36 was buy this new heat shield offered [spam] and that it got him the speed he wanted. I decided to buy it too because it sounded like good idea. It was actually! Its fantastic, it’s a lot better than the cheap-o ones they have at the stores, the quality of this one is a lot better and it actually creates, what they call a ‘box’ effect, so the hot air REALLY doesn’t get to the engine, and all I get is cold air. I recommend that ya’ll get it, it’s a real good investment.
